ReflecTrace: Touchless Hover Interaction on Commodity Smartphones via Corneal Reflection

We propose an approach to detect finger hover inputs on a smartphone screen using corneal reflection images captured by the device’s built-in front camera. This method requires no external sensors or hardware, enabling hover input detection in the near-screen space that is not directly visible to the camera. By levera…

DuoTouch: Passive Two-Footprint Attachments Using Binary Sequences to Extend Touch Interaction

DuoTouch is a passive attachment for capacitive touch panels that adds tangible input while minimizing content occlusion and loss of input area. It uses two contact footprints and two traces to encode motion as binary sequences and runs on unmodified devices through standard touch APIs. We present two configurations w…

FoodSkin: Fabricating Edible Gold Leaf Circuits on Food Surfaces

We present FoodSkin, a technique for adding interactive elements to foods by implementing edible circuits on the surface of the food. The circuit is easily fabricated using commercially available materials. Existing approaches to enhance the eating experience, such as presenting an electrical taste by making food part…

Behavioral Differences between Tap and Swipe: Observations on Time, Error, Touch-point Distribution, and Trajectory for Tap-and-swipe Enabled Targets

Existing guidelines for designing targets on smartphones often focus on single-tap operations for accurate selection. However, smartphone interfaces can support both tap and swipe actions. We explored user-performance differences between tap and swipe in two crowdsourced experiments using bar and square targets. Resul…

Better Definition and Calculation of Throughput and Effective Parameters for Steering to Account for Subjective Speed-accuracy Tradeoffs

In Fitts' law studies to investigate pointing, throughput is used to characterize the performance of input devices and users, which is claimed to be independent of task difficulty or the user's subjective speed-accuracy bias. While throughput has been recognized as a useful metric for target-pointing tasks, the corres…

Efficient Adaptive Beacon Deployment Optimization for Indoor Crowd Monitoring Applications

"The indoor crowd density monitoring system using BLE beacons is one of the effective ways to prevent overcrowded indoor situations. The indoor crowd density monitoring system consists of a mobile application at the user's side and the beacon sensor network as the infrastructure. Since the performance of crowd density…

Acoustic+Pose: Adding Input Modality to Smartphones with Near-Surface Hand-Pose Recognition using Acoustic Surface

To achieve mid-air interactions for smartphones, acoustic-sensing, a technique using the built-in speaker and microphone of smart- phones, is promising. However, detecting hand poses on the near- surface of touchscreens remains challenging due to the arrange- ment of the built-in speaker and microphone. To address thi…

Detecting Thumb-Posture for One-handed Interactions with Smartphone using Acoustic Sensing

This paper presents a novel approach for expanding one-handed interactions using the thumb positioned above the smartphone screen. Our approach is based on acoustic sensing, a technique for leveraging the built-in speaker and microphone of the smartphone without requiring additional sensors or attachments. We explored…

Single-tap Latency Reduction with Single- or Double- tap Prediction

Touch surfaces are widely utilized for smartphones, tablet PCs, and laptops (touchpad), and single and double taps are the most basic and common operations on them. The detection of single or double taps causes the {\it single-tap latency problem}, which creates a bottleneck in terms of the sensitivity of touch input…

Tuning Endpoint-variability Parameters by Observed Error Rates to Obtain Better Prediction Accuracy of Pointing Misses

Error rates (ERs) in target-pointing tasks are typically modelled in two steps: predicting the click-point variability (sigma) based on target sizes and then computing the probability that a click falls outside a target. This is an indirect approach if the researcher's purpose is to achieve the accurate prediction of…
